TRUCK ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 679,621, dated July 30,1901.

Application filed April 2011901. Serial No. 561729- (No model.)

To all whom, it may concern.- I

Be it known that I, BYRON HORATIO HUL- BURD, a citizen of the UnitedStates, and a resident of Sacramento, in the county of Sacramento andState of California, have made a certain new and useful Invention inTruck Attachments; and I declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledI0 in the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to letters of referencemarked thereon, which form a part of this specification. Figure 1 is aperspective view showing my invention as applied, the attachment beingshown as swung outwardly and braced. Fig. 2 is a central longitudinalsection of a truck having myinvention applied thereto, the attachmentbeing shown as swung inwardly. Fig. 3 is a bottom plan view of theattachment. Fig. i is detail perspective view of the axle-catch. Fig. 5is a cross-section on the line 5 5, Fig. 3.

The invention relates to attachments for warehouse-trucks and itconsists in the novel construction and combination of parts, ashereinafter set forth.

In the accompanying drawings, the letter A designates an ordinary truckhaving the usual side bars CL ct and front scoop or flange b. The wheelsare indicated at c, and the axle at e.

The object of the invention is to provide an attachment for the truckwhich will serve as an upright back or abutment when the scoop is shovedunder a pile of boxes, such back or abutment being at right angles tothe plane of the scoop.

The letters F F indicate the bars or posts, which are parallel to eachother and held in proper relative position by means of the transversebolts 9 g, which pass through openings h h in said bars near their upperand lower ends. The bolts are threaded at each end portion, the threadsextending sufficiently near to the middle of each bar to provide foradjustment to the narrowest trucks, while the bolts are long enough toprovide for adj ustment to the widest trucks. At each opening h eachbolt is provided with an inner nut 7t" and an outer nut Z, whereby theadjustment is secured. These bars F are preferably made of angle-iron,as shown; but they may be made of wood. One or both of the bars shouldbe provided with a handhold m. Near its lower end the frame thusprovided, consisting of the bars and transverse bolts, is provided withadetachable orhinged catch P, which is usually attached to the lowertransverse bolt and is designed to be connected to the axle of the truckwhen the attachment is secured thereto. This catch secures the lower endof the attachment-frame in position, and its upper end is attached tothe side bars of the truck by means of the brace-hooks or brace-catchesIt R, whicharc pivoted to the frame-bars, their catch ends engagingsuitable studs or hearings on the side bars of the truck. Then the frameis attached to the truck in the manner indicated,

it is securely braced in position, extending at right angles to theplane of the scoop.

This attachment can be readily applied to any warehouse-truck of thecharacter referred 7 to in a few moments and can be as readily andquickly detached when not required for use.

The attachment is especially designed for use in moving piles of boxescontaining print or articles of delicate character, as it can be appliedto the pile in such a manner as to afford an upright bearing throughoutthe extent of the pile when the scoop is shoved under the lowermost boxthereof.

The flexible axle-catch is for the purpose of limiting the outwardmovement of the attachment, while the upper brace-catches are adaptedfor detachable connection with the truck-frame for the purpose ofconverting the truck into one of the ordinary variety, when the parallelbars F F of the attachment will rest upon the side rails of the truck.(See Fig. 2.)

The bars F of the truck attachment are in- 5 wardly notched at theirlower end portions at ff to engage the front scoop or flange of thetruck. In this way these bars rest when elevated upon such scoop orflange, are secured in place, and transverse adjustment thereof I00 isstill allowed.

Having described this invention, what I claim, and desire to secure byLetters Patent, 1s

1. The combination with a truck, of the attachment therefor, having theparallel bars adapted to have a pivotal movement with respect to thetruck, the flexible axle connection limiting outward movement of theattachment, and the upper detachable brace connection, substantially asspecified.

2. The combination with a truck, of the at tachment therefor, having theparallel bars adapted to have a pivotal movement with respect to thetruck, the flexible axle connection limiting outward movement of theattachment, means for adjusting said bars toward and away from eachother, and the upper brace connection adapted to have a detachableengagement with the truck, substantially as specified.

3. The combination with a truck, of the attachment therefor, having theparallel bars of angle form in cross-section, adapted to have a pivotalmovement with respect to the truck, and adapted to rest upon the siderails of the truck, and the upper brace connection adapted to have adetachable engagement with the truck, substantially as specified.

4:. The combination with a truck, of the attachment therefor, consistingof the parallel bars having inwardly-extending notches at their lowerend portions engaging the front scoop or flange of the truck, means foradjusting said bars toward and away from each other, and means fordetachably supporting said bars in upright position away from thetruck-frame, substantially as specified.

5. The combination with a truck of the character described, of theadjustable parallel bars, their transverse connecting and adjustingbolts, the detachable axle-catch, and the detachable brace-catches,substantially as specified.

In testimony whereof I afiiX my signature in presence of two witnesses.
